Printing System

1. A print controlling apparatus for controlling printing processing by using a printing right token in which printing limitation information is defined to force a user to use a predetermined printing setting, the apparatus comprising: an inputting unit for inputting an exceptional condition in which printing of image data is forced to be executed in a color print mode when the image data includes a digital watermark even if the predetermined printing setting defines a forced-monochrome-printing setting in which printing is forced to be executed in a monochrome print mode; a determination unit for determining whether a conflict occurs between the forced-monochrome-printing setting defined by the predetermined printing setting and a printing setting defined by the exceptional condition input by said inputting unit, wherein said determination unit determines that a conflict occurs if a print instruction is given for image data including a digital watermark when the predetermined printing setting defines the forced-monochrome-printing setting; and an executing unit for executing printing of the image data including a digital watermark in the color print mode, if the determination unit determines that the conflict occurs, even when the predetermined printing setting defines the forced-monochrome-printing setting.

2. A method for a print controlling apparatus for controlling printing processing by using a printing right token in which printing limitation information is defined to force a user to use a predetermined printing setting, the method comprising: an inputting step of inputting an exceptional condition in which printing of image data is forced to be executed in a color print mode when the image data includes a digital watermark even if the predetermined printing setting defines a forced-monochrome-printing setting in which printing is forced to be executed in a monochrome print mode; a determining step of determining whether a conflict occurs between the forced-monochrome-printing setting defined by the predetermined printing setting and a printing setting defined by the exceptional condition input in said inputting step, wherein said determination unit determines that a conflict occurs if a print instruction is given for image data including a digital watermark when the predetermined printing setting defines the forced-monochrome-printing setting; and an executing step of executing printing of the image data including a digital watermark in the color print mode, if it is determined in the determining step that the conflict occurs, even when the predetermined printing setting defines the forced-monochrome-printing setting.

3. A computer-readable medium storing a computer program for a print controlling apparatus for controlling printing processing by using a printing right token in which printing limitation information is defined to force a user to use a predetermined printing setting, the program comprising: an inputting step of inputting an exceptional condition in which printing of image data is forced to be executed in a color print mode when the image data includes a digital watermark even if the predetermined printing setting defines a forced-monochrome-printing setting in which printing is forced to be executed in a monochrome print mode; a determining step of determining whether a conflict occurs between the forced-monochrome-printing setting defined by the predetermined printing setting and a printing setting defined by the exceptional condition input by said inputting unit. wherein said determination unit determines that a conflict occurs if a print instruction is given for image data including a digital watermark when the predetermined printing setting defines the forced-monochrome-printing setting; and an executing step of executing printing of the image data including a digital watermark in the color print mode, if it is determined in the determining step that the conflict occurs, even when the predetermined printing setting defines the forced-monochrome-printing setting.
